In slide 11, the wave form in and the out wave aren't the same. Hopefully if the double conversion is performed correctly, they would be the same. Or is this just an illustration and isn't meant to be scaled, etc. I would also think it would be more complex to design a DAC than a ADC. Yes/no?

Thanks Max! I like your approach! It seems that you could add more beef to these segments - you have our interest and then you drop us off - like watching a TV show that ends with a clif hanger! Please request more time, and I was unable to see information in the window. I clixked on HTML and still could not see. I'll update my Flash player and see if that helps. See you tomorrow and thanks again. HCH

I'm really sorry about this -- now I'm up to th emessages saying what everyine is doing, like looking for a refresher course or being a student -- this could take ages before I'm caught up -- I think we'll have to leave it until tomorrow -- so if you have any questions from today's course -- post them here and I'll read them later and i'll try to answer them tomorrow

Ah ... now I'm seeing the message from folks saying that they are seeing the first image I put up -- give me strength!!!

how to track the low frequency signal(15 to 30 Hz) from beneath the ground surface accurately?

We use pig transmitters that emit low frequency signals and a receiver is supposed to accurately track that signal but our receiver catches any undesired low frequency signal which is not necessarily the one from the transmitter. What is the ideal way to get rid of this problem?

@You will have to be patient with me -- I lost my broswer and now I'm back it's refreshing every message ... one ... at .... a ... time .... it's painfully slow -- I'm still seeing the oribginal ones saying "hi" -- give me a minute or two ...

How does band width of MSO relate to clock speed of mpu or mcu in sut? e.g. if using an mcu at 100MHz, what is the minimum bandwidth mso i can use to get a clear picture of what's happening in the overall device? Thanks.

I just messed up my browser and lost all the messages -- re th eperson who can;t see that analog computer (or any of the images) -- email me directly at max@clivemaxfield.com and I'll email you back the image

@luizcosta: thanks for the info! :) I'm just remembering my physics course which attempted to be taught as both Algebraic-based and Calculus-based at the same time, and certain things seemed better fit to one or the other...

dont confuse analog or early computers with OEM (off line electronic machines) which processed punched cards. a different machine for different functions such as: sorting, printing, merging, calculating

I'm sitting in because Max is so entertaining. My professional carreer in electronics began in the 70's with tubes (valves for Max). tubes. Have been designing analog, digital and embedded control systems.

I listened to it again at least twice after work because I was unable to take notes and keep up with the live stream, so today I will just listen and try to absorb as much as I can live, but tonight will really get into it.

Industrial workplaces are governed by OSHA rules, but this isnít to say that rules are always followed. While injuries happen on production floors for a variety of reasons, of the top 10 OSHA rules that are most often ignored in industrial settings, two directly involve machine design: lockout/tagout procedures (LO/TO) and machine guarding.
